Part A: a. the point 3 units to the left of 7

Part B: b. -4

Step-by-step explanation:

Part A: The expression can be simplified into 7 - 3, and when you subtract a number, you go left on the number line, so the point 3 left of 7

Part B: 7 - 3 = 4, and to get to 0 from 4, you need to subtract 4 or add -4

Answer:

y=3/4x+1

Step-by-step explanation:

If you rearrange the given equation to slope intercept form, you'll find the slope to be -4/3. If a line is perpendicular to another it'll have the opposite reciprocal for a slope, meaning the new line's slope would be 3/4. If you plug 3/4 and the given point's x and y value into slope intercept form you'll find the b value or y intercept to be 1. Since you now have the slope and the y intercept you can determine the equation to be y=3/4x+1. Hope this helps!

A painter leans an 18 foot ladder against the house so that the base of the ladder is 4 feet away from the wall. Approximately how far up the side of the house does the ladder reach?​

Answers

Answer: 17.5ft

Step-by-step explanation:

Use Pythagorean theorem

A^2 + B^2 = c^2 where c is the hypotenuse

The ladder leaning against the wall is the hypotenuse.

4^2 + b^2 = 18^2

16 + b^2 = 324

324-16 = b^2

308 = b^2

B = 17.5ft

Evaluating Polynomials:

b. f(-3) = -239  

c. f(2)² = 3125

Factoring Polynomials:

a. (x + 1)(x² - 5x + 6) = (x + 1)(x - 3)(x - 2)  

b. (x² - x - 6)(x² + 6x + 9) = (x - 3)(x + 2)(x + 3)(x + 3)

A polynomial can be evaluated and factored by long division, factoring and synthetic division methods.

1. Evaluate polynomials

[tex]\mathbf{f(x) = x^4 - 7x^2 + 2x - 6}[/tex]

Substitute 1 for x

[tex]\mathbf{f(1) = 1^4 - 7(1)^2 + 2(1) - 6}[/tex]

[tex]\mathbf{f(1) = 1 - 7 + 2 - 6}[/tex]

[tex]\mathbf{f(1) = -10}[/tex]

[tex]\mathbf{f(x) = 10x^3 + 4x^2 - 5}[/tex]

Substitute -3 for x

[tex]\mathbf{f(-3) = 10(-3)^3 + 4(-3)^2 - 5}[/tex]

[tex]\mathbf{f(-3) = -270 + 36 - 5}[/tex]

[tex]\mathbf{f(-3) = -239}[/tex]

[tex]\mathbf{f(x) =x^4 + 5x^3 - 2x + 3}[/tex]

Substitute 2 for x

[tex]\mathbf{f(2) =2^4 + 5(2)^3 - 2(2) + 3}[/tex]

[tex]\mathbf{f(2) =16 + 40 - 4 + 3}[/tex]

[tex]\mathbf{f(2) =55}[/tex]

Square both sides

[tex]\mathbf{f(2)^2 =3025}[/tex]

Hence, the results of evaluating the polynomials are [tex]\mathbf{f(1) = -10}[/tex], [tex]\mathbf{f(-3) = -239}[/tex] and [tex]\mathbf{f(2)^2 =3025}[/tex]

2. Factor the polynomials

[tex]\mathbf{(x + 1)(x^2 - 5x + 6)}[/tex]

Expand

[tex]\mathbf{(x + 1)(x^2 - 5x + 6) =(x + 1)(x^2 - 2x - 3x + 6) }[/tex]

Factorize

[tex]\mathbf{(x + 1)(x^2 - 5x + 6) =(x + 1)(x(x - 2) - 3(x - 2) )}[/tex]

Factor out x - 2

[tex]\mathbf{(x + 1)(x^2 - 5x + 6) =(x + 1)(x - 3)(x - 2) }[/tex]

[tex]\mathbf{(x^2 - x - 6)(x^2 + 6x + 9)}[/tex]

Expand

[tex]\mathbf{(x^2 - x - 6)(x^2 + 6x + 9) = (x^2 +2x - 3x - 6)(x^2 + 3x +3x + 9)}[/tex]

Factorize

[tex]\mathbf{(x^2 - x - 6)(x^2 + 6x + 9) = [x(x +2) - 3(x + 2)][x(x + 3) +3(x + 3)]}[/tex]

Factor out x + 2 and x + 3

[tex]\mathbf{(x^2 - x - 6)(x^2 + 6x + 9) = [(x - 3) (x + 2)][(x + 3)(x + 3)]}[/tex]

Remove square brackets

[tex]\mathbf{(x^2 - x - 6)(x^2 + 6x + 9) = (x - 3) (x + 2)(x + 3)(x + 3)}[/tex]

[tex]\mathbf{x^3 + 3x^2 - 4x - 12}[/tex]

Factorize

[tex]\mathbf{x^3 + 3x^2 - 4x - 12 = x^2(x + 3) - 4(x + 3)}[/tex]

Factor out x + 3

[tex]\mathbf{x^3 + 3x^2 - 4x - 12 = (x^2 -4) (x + 3)}[/tex]

Apply the difference of two squares

[tex]\mathbf{x^3 + 3x^2 - 4x - 12 = (x -2)(x+2) (x + 3)}[/tex]

Hence, the results of factoring the polynomials are [tex]\mathbf{(x + 1)(x^2 - 5x + 6) =(x + 1)(x - 3)(x - 2) }[/tex], [tex]\mathbf{(x^2 - x - 6)(x^2 + 6x + 9) = (x - 3) (x + 2)(x + 3)(x + 3)}[/tex] and [tex]\mathbf{x^3 + 3x^2 - 4x - 12 = (x -2)(x+2) (x + 3)}[/tex]

Question

Use the properties of exponents to simplify the expression: [tex]25^{\frac{3}{2}}[/tex]

Answer:

[tex]25^{\frac{3}{2}} = 125[/tex]\

Step-by-step explanation:

Given

[tex]25^{\frac{3}{2}}[/tex]

Required

Simplify

[tex]25^{\frac{3}{2}}[/tex]

Apply the following law of indices

[tex]a^{\frac{m}{n}} = (a^m)^{\frac{1}{n}}[/tex]

So, the expression becomes

[tex]25^{\frac{3}{2}} = (25^3)^{\frac{1}{2}}[/tex]

Express [tex]25^3[/tex] as 15625

[tex]25^{\frac{3}{2}} = (15625)^{\frac{1}{2}}[/tex]

In indices: [tex]a^{\frac{1}{2}} = \sqrt a[/tex]

So, we have:

[tex]25^{\frac{3}{2}} = \sqrt{15625[/tex]

[tex]25^{\frac{3}{2}} = 125[/tex]

System of Equations : Money

Damian has been saving coins he finds on the ground for several months. So far he has found 37 coins that are either pennies or nickels. The combined value of his found pennies and nickels currently is $1.09. What is the system of linear equations, written using standard form, represents the situation if Damian found p pennies and n nickels.​

Answers

Answer:

18 nickles 19 pennies

Step-by-step explanation:

value of 1 penny=$0.01

value of 1 nickle=$0.05

0.01p+0.05n=1.09

p+n=37

there are two methods for this system

I.substitution

p+n=37

p=37-n

we replace p in the first relation

0.01(37-n)+0.05n=1.09

0.37-0.01n+0.05n=1.09

0.04n=0.72

n=18 nickels

p+18=37

p=37-18=19 pennies

II.reduction

0.01p+0.05n=1.09

p+n=37

we multiply the second equation by 100

p+5n=109

p+n=37

we calculate the difference between the two relations

p-p+5n-n=109-37

4n=72

n=18

p+18=37

p=19
